Windows 7: Extended Desktop Blurred on HDTV

Windows 7 64 Bit
Extended Desktop Blurred on HDTV


I have finally managed to get some of my games to work on my HDTV which was one of my issues originally.

I have a ATI Radeon HD4350 PCI card which I have hooked up to my TV via the HDMI slot. I have the latest ATI Catalyst 10.3 (I think)

The problem now is that when I switch the display from my monitor to my 50 inch HDTV it works fine but if I extend the desktop to the HDTV the display is blurred on my HDTV and the picture on my monitor doesn't show in it's entirety (just the desktop background)

I have tried messing about with the resolutions and refresh rates in the ATI Catalyst but it just doesn't work.

My monitor is set to 1024x768 30hz refresh and my HDTV is set to a standard 1080 resolution as recommended in the Catalyst. I have also tried a 720 resolution but it's still blurred.

It seems as if the graphics card can't extend the desktop to a resolution that my TV recognises.

Maybe it's a issue with my TV?

Can anyone help me with the correct resolutions and refresh rates I need as the
Catalyst one's don't work.

You set the HDTV at an extended 1080p resolution. Then you open CCC - Desktop & Displays - Right Click the small HDTV at the bottom - Configure - Scalling - then set the Overscan/Underscan to 0%.
